9 Claims.

This invention relates to a construction which will permit the utilization and elimination of the odors and gases from cooking foods, and as such, the primary object of this. invention is to pro- 5 vide a method and means whereby said gases and odors may be burned or purified efficiently by the gas burner of the stove upon which said foods are being cooked.

It is a further object of the present invention to provide a construction of the character described which will permit the introduction of gases and odors from cooking foods to be introduced into the gas. burner upon which said foods are cooking at the air and fuel gas inlet of said burner to be passed with the air and gas to the flame to be burned thereat.

It is a further object of the present invention to provide means for the introduction of odors from cooking foods into the gas burner upon which said foods are being cooked, whereby the odors are thoroughly mixed with the gas and air being injected into said burner and burned or purified and deodorized at the flame thereof.

It is a further object of the present invention to provide a device of the character described, which will have included novel means for providing attachment of the various cooking utensils of a stove thereto, to permit the utilization of the odors and gases evolved from foods cooking in said utensils.

A still further object of the present invention is to provide a method, whereby the gases and odors evolved from foods cooking over a gas burner may be utilized to augment the flame of said burner and at the same time be deodorized so' that no unpleasant smells result from said cooking foods.

A still further object of the present invention is to provide a method whereby the gases odors evolved from foods cooking over a gas burner flame may be burnedlat the flame to augment said flame and destroy the unpleasant smell of said gases and odors, said method comprising the steps of one, gathering said gases and odors, two, leading same to the inlet end of said burner, and three, injecting same into the mixing chamber of said end of the burner to be commingled with the entering air and fuel gas being projected or drawn into said chamber to be passed to the flame and burned thereat.

The foregoing and other objects will become more apparent from the description which follows, in which my invention will be set forth in its complete disclosure with regard to construction, arrangement, and combination of parts, the same being illustrated in the accompanying drawing and pointed out more specifically in the claims. It should be apparent that the invention may be changed in form, size, proportion and general configuration without departure from the general spirit thereof, thus utilizing all the expressed and implied advantages and features thereof which are obviously inherent thereto.

For the purposes of illustration, I have presented in the drawing preferred embodiments. of my invention, the description and inspection of which will serve to more completely and clearly apprise one of my invention and the modes of construction, assembly and operation thereof, making same more easily understood and appreciated.

Referring now to the drawing in which characters of reference used in connection with corresponding or similar portions throughout the several figures of the drawing refer to parts in common of the invention:

Fig. 1 is a sectional view of an embodiment of my invention associated with a gas stove;

Fig. 2 is modification of a cooking utensil designed to be utilized with my invention;

Fig. 3 is a fragmentary view of a portion of the modification of my invention depicted in Fig. 4; Fig. 4 is a modification of my invention associated with the burner system of a household gas range.

Generally, my invention consists of a novel method for utilizing the odors evolved from foods cooking over gas burners, which comprises gathering same, piping same to the inlet of said gas burners, and injecting same into said burners along with the air, and gas normally projected therein to be carried to the flame portions to be burned thereat. Further, the invention comprises novel means for practicing said method.

More specifically, the reference character iii designates generally a cooking utensil provided with a substantially air-tight cover ll. Said utensil I is shown in Fig. l, disposed upon the top [2 of a gas range l3 on a grate it thereof, over the flame l5 of one of the burners i6. Said cover I I is provided with a member H, which serves to gather the gases and odors generated by the food cooking in said utensil Ill. The odors and gases from the cooking food are gathered by being drawn into the portion l3 of the member I! in a manner to be described, as designated by the arrows.

The burner I6 is fed with fuel gas as its chief fuel, said fuel gas being projected into the mixing chamber [9 of the burner by reason of the pressure in the gas main, which leads to the feed conduit 20 of the gas range. The flow of fuel gas to the burner is controlled by the valve 2| in the injector pipe 22. Draft is assured to the flame I 5 by the air vent 23, the size of which may be controlled in the usual conventional manner.

A second conduit 24 is fixed to the burner to lead into the mixing chamber l9. It is disposed so that the member I! may be attached to it firmly, but removably as desired by the user. To facilitate the attachment, the member I1 is provided with a wide-mouthed opening 25 in the downwardly bent portion 26, in which a resilient member 21 is disposed. Said member 21 may be of rubber or the like to enable the same to be easily slipped over the free end of the conduit 24 in an airtight connection. The conduit 24 is provided at the bottom thereof with a bend 28, which serves to catch any moisture which may have condensed from steam passing over through said member I! with the odors and gases from the cooking food.

I have found that the draft caused by the combined action of the flame l5 and the air vent 23 are sufficient to cause all of the odors and gases from the cooking foods to be drawn into the mixing chamber l9 via the member I! and the conduit 24. I have found that the injection of the gases and odors from the foods into the mixing chamber l9 rather than at any other place, as, for example, directly into the flame, serves to completely commingle said. gases and odors with the air being drawn in through the vent 23 and the fuel gas being projected in through the injector pipe 22 to make a completely homogeneous mixture. This mixture is burned very efficiently at the flame l5, consuming most of the gases and odors along with the fuel gas, and purifying and deodorizing the non-inflammable portions thereof.

It will be apparent that all unpleasant smells can thus be eliminated from the kitchen, while at the same time cooking is rendered more economical, since a great portion of the gases and odors which evolve from the cooking food either are combustible or aid in the combustion of the fuel gas.

An important feature of my invention is the fact that it can be installed in any modern gas range without any change or alteration therein other than providing an opening in the mixing chamber 59 for the end of the conduit 24.

While Fig. l discloses a cooking utensil Ill, which is provided on its cover H with the conducting member l'l, Fig. 2 shows a modification of the cooking utensil which will operate as well as that shown in Fig. 1. Said utensil 30 of Fig. 2 is provided with a hollow handle 3| through which the member I! is led. This eliminates the necessity of attachment of the member to the cover which the user is free to remove as often as necessary without detachment of the member H from the conduit 24.

Fig. 4 depicts a system whereby the odors and gases may be led to outlets at the rear of the gas range and thence led to the burners. The gas range is provided with the conventional feed conduit .0 leading from the gas main, to which are connected the burners 4| and the pilot light 42.

Said burners 41 are provided with mixing chambers 43 and air vents 44, and are connected to the feed conduit 4 by means of the injector vention.

pipe 45. A valve 46' is provided in said pipe 45 for the control of the fuel gas flow.

A second conduit 46 is disposed below said conduit 40 and is provided with a plurality of feed conduits ll, which are connected to the mixing chambers 42 of the burners 4!. In each of these conduits 41, a valve 48 is provided for the flow of gases from the cooking foods. Said valves 48 are coupled to the respective valves 46 in the conduits 45 of each burner, so that the pairs of valves may be operated in tandem as desired by the respective handles 49.

Said conduit 46 is connected by the pipe 50 to the rear conduit 5|, which is provided with a plurality of feed conduits 52. The feed conduits have valves 53, by which the flow of food gases through the pipe 50 may be controlled.

In this manner, there may be provided means whereby a plurality of cooking utensils may pass their gases and odors to the feed conduit 46 and thence to the burner, utilizing same. It is obvious that the entire system may be concealed, except for the nozzles and valves of the conduits 52. Any steam which may condense in the system may be periodically drained off by means of the petcock 54.

It will be seen that I have provided novel and efficient means, whereby the odors and gases evolved from cooking foods may be eliminated from the atmosphere of the kitchen and instead be used to augment the cooking flame and be purified and deodorized thereby.

Since it is believed that the above disclosure of the construction of the preferred embodiments of my invention will obviously set forth the entire and complete operation thereof, further explanation will be dispensed with.

While reference and disclosure have been made with regard to more or less specific embodiments of my invention, it is to be noted that the details and less important features are capable of assuming diversified forms, and wide variations without departing from the purview of my in I do not Wish to be limited in my Letters Patent to specificities as disclosed, but rather would be protected for the broad generalities to which my invention obviously entitles me and which are herewith stated in the appended claims.
